A tour operator has flown a pet goat over the world-famous Horizontal Falls, in Western Australia's Kimberley.

Tour operator Troy Thomas was set a challenge by his staff to try to fly Gary over the falls in a sea plane, and follow it up with a speed boat ride.

Gary is in the Kimberley with his owner, comedian Jimbo Bazoobi.

Mr Thomas says the logistics were a nightmare, but it all paid off, as Gary the goat appeared to enjoy the visit.

"I contacted a few of the authorities and went through what was necessary to get Gary out here - building him a box and getting him all strapped into the plane," he said.

"He was VIP, he had the whole plane to himself on the way out.

"It was pretty interesting; we had to have a custom built goat box built for him and we needed a forklift to assist getting that into the plane.

"He's been pretty well behaved actually."

Gary did all the things the other tourists did - he donned a hat, nametag and lifejacket and took a speed boat ride through the falls, and helped feed the nurse sharks that swim up to the platform decking.

Jimbo also came along for the ride.

Four years ago, Jimbo bought Gary for a case of beer while doing a show in Gingin.
